my homelite trimmer was running perfect then in the middle of using it - it died and I haven't been able to get it started again. I changed the gas, replaced the plug, checked the muffler, cleaned the air filter. What else can I do?
I would take the filter off completely and try starting. Also was the trimmer running funny when it kicked out. I sounds like an electrical thing...just kicks out clean.
But first you need to know if there is spark.
Also make sure all your bolts/bits are tight. I saw one of those vibrate the bolts loose and there was no seal at the carb. I've also had the fun of diagnosing one for a friend where the actual jug came apart! Loctite is your friend with these guys!
